and also monitors closely those that are using it for manipulating its algorithms.
Google has been moving toward letting its algorithms (not authors or publishers) determine what is or isn't "authored"--e.g., by scanning for bylines. Also, the fact that Google has made authorship markup automatic on large publishing platforms like WordPress.com and TypePad (where bloggers can verify their authorship credentials simply by logging in with Google+) suggests that Google doesn't regard Authorship adopters as "manipulators."
I don't see them using it as a ranking signal soon.
"Soon" is a relative term.
